.4, Claims. (Cl. 221-62) This invention relates to powder dispensingdevices, and more particularly for devices adapted to dispense powderedsoap and the like.

One of the objects of the invention is'to provide a device of thischaracter which when operated will permit not only finely powderedparticles to be dispensed, but also heavier or caked lumps.

Another object of the invention is to provide a hopper provided with adownwardly tapering or inverted conical portion, and a centrally locatedplunger yieldably mounted therein and provided with a closure membertapering in the same direction as the hopper but at a lesser degree soas to make only line contact with the said tapered hopper portion whenin closed or non-dispensing position.

A further object of the invention is to provide a powder can orreceptacle especially adapted for use with the said dispensing device.

Another object is to produce a device of the character described inwhich the maximum simplicity of construction and operation is secured.

Other objects and advantages'will appear as the nature of theimprovements is better understood, the invention consistingsubstantially in the novel arrangement and co-relation of parts hereinfully described, and illustrated in the accompanying drawing, whereinsimilar reference characters are used to describe corresponding partsthroughout the several views, and then finally pointed out andspecifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventiveconcept suggests a practical embodiment thereof, but the invention isnot to be restricted to the exact details of this disclosure, and thelatter, therefore, is to be understood from an illustrative, rather thana restrictive standpoint.

The inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which, for the purpose of illustration,is shown in the accompanying drawing, in which Figure 1 is a view inside elevation of our improved dispensing device.

Figure 2 is a longitudinal cross sectional view of the lower portionthereof, with the parts shown in closed or non-dispensing position.

Figure 3 is a similar view to Figure 2 but with the parts shown inactuated or dispensing position.

Figure 4 is a sectional view taken on line 44 Figure 1 and Figure 5 isaview in side elevation of the powderreceptacle or container.

Referring now to the drawing in detail 10 indicates a hopper provided atthe top thereof with a cylindricalportion 11,the lower end of which isprovided with a head 12 from which depends a conical or funnel shapedend portion 13. A

'cross plate or bar 14 provided with a central opening 15 is snappedinto the interior of the be'ad1-2 and together withthe lower tunnel opening 16 acts as a centralizer for a valve structure The "saidvalve-structure comprises a lower stem 18, a valve head or plug 19 whichtapers in the same general direction as the hopper 13 7 but at a lesserdegree, an upper stem 20 whichtapersupwardly at 21 and terminates in acylindrical portion 22 whose diameter is somewhat smaller than theorifice or opening 15 in the plate 14 through which it passes." A coiledspring 23 exerts a pressure between the underside of the plate 14 andthe valve head 19 to maintain the device in closed position asillustrated in Figures 1 and 2.

It will be seen by referring to Figure 2 that 90 due to the fact thatboth the hopper 13 and the valve head 19 are tapered in the samedirection, but at different angles only a line contact is formed betweenthe said parts at the opening 16, thus providing clean cut-off means, orin other words no clogging of the valve opening is possible. It willfurther be seen that due to this arrangement of hopper and valve head, awide passageway is formed between the hopper wall and valve head for thefree passage of the contents of the device when actuated to the Figure 3position. Inasmuch as the stem portion 22 is of smaller diameter thantheopening 15 in the plate 14, it will be seen that when the valvemechanism is pressed upwardly and as soon as the contact between thevalve head and opening 16 is broken the entire valve mechanism may betilted to one side to provide a still wider passageway for anycaked orlumped particles of soap.

The interior of the cylindrical portion 11 of the hopper is'providedwith a projection 30 to fit into a cutout 31 at the mouth end of apowder receptacle or can 32 which is of the same diameter as theinterior of the said cylindrical hopper portion 11. This provides meansfor interlocking the container and dispensing device as well as foralways maintaining the advertising matter on the container where it isalways visible.

The container 32 is provided with a lid or cover 34 which normallycovers the slot or cutout 31 to prevent loss of the contents thereof.The advertising material 33 is printed on the container in invertedposition in relation to the mouth or cover end thereof so that it willbe right side up when the container is inserted into the dispensingdevice.

The provision of the slot 31, the projection 30 and the invertedprinting of the advertising matter provide means for insuring the use ofonly the products of the manufacturer for whom the dispensing device isintended.

A bracket 36, comprising a plate 37 and a pair of spring arms 38 whichare adapted to engage the cylindrical portion 11 of the hopper forms a'support for the device. The plate 3'7 is provided with a pair of holes39 for securing the bracket to wall or other support.

From the foregoing, it will be seen that we have provided a simple yetefiicient dispensing device which will dispense powdered soap and thelike without becoming clogged or otherwise get out of order.

Having described our invention what we claim as new and desire to secureby Letters Patent is:

l. A dispensing device, comprising a hopper, a downwardly taperingconical shaped portion at the bottom thereof provided with a dischargeopening, a plate in the hopper having a perforation therein in line withthe discharge opening, a conical valve head; normallv closing thedischarge opening and tapered in the same direction as the conicalhopper portion but at a lesser degree, a stem depending from the valvehead, a

and plate.

2. A dispensing device, comprising aihopper, 9.

downwardly tapering conical shaped portion at the bottom thereofprovided with a discharge opening, a plate in the hopper having aperforation therein in line with the discharge opening, a conical valvehead, normally closing the discharge opening and tapered in the samedirection as the conical hopper portion but at a lesser degree, andextending below the said discharge opening, a stem depending from thevalve head, a second stem extending upwardly from the valve head andpassing loosely through the plate perforation, and spring means betweenthe said head and plate.

3. A dispensing device comprising a hopper, provided with a dischargeopening at the bottom thereof, a plate in the hopper having aperforation in line with the discharge opening, a valve movably andtiltably mounted in the said discharge-opening and plate perforation,the said valve comprising a tapering valve head normally closing thedischarge opening and extending outwardly thereof, a stem extendingupwardly from the valve head and passing loosely through the plateperforation and a spring for normally maintaining the valve head inclosing contact with the discharge opening.

4. A dispensing device, comprising a hopper provided with a dischargeopening at the bottom thereof, a plate in the hopper having aperforation in line with the discharge opening, a valve head normallyclosing the discharge opening and extending outwardly thereof, a stemextending upwardly from the valve head and passing loosely through theplate perforation, a tapering portion on the stem for the purposespecified, and spring means for normally maintaining the valve head inclosing contact with the discharge open- JAMES P.
